NCT03201211

Brief Summary

The purpose of this long-term follow-up of a Phase I study is to evaluate the kinetics of the antibody response to NTHi-Mcat antigens and long-term safety, in subjects aged between 50-71 years at the time of enrolment in the NTHi-Mcat-001 study. These subjects were previously exposed to two adjuvanted formulations of the NTHi-Mcat vaccine administered according to a 0, 2 months schedule in the NTHi-Mcat-001 (201281) study. The subjects that had received saline placebo controls will also be included in this follow-up study to make comparisons with the investigational vaccines. No vaccinations will be administered in this trial.

  • Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g. return for follow-up visits). And subjects' Legally Acceptable Representative(s) \[LAR(s)\] who, in the opinion of the investigator, can and will comply, with the requirements of the protocol.
  • Written informed consent obtained from the subject/ LAR(s) of the subject prior to performance of any study specific procedure.

You may not qualify if:

  • Use of any investigational or non-registered product (drug or vaccine) during the period starting 30 days before the first follow-up study visit (Month 19 to Month 20), or planned use during the study period.
  • Chronic administration (defined as more than 14 days in total) of immunosuppressants or other immune-modifying drugs since the end of the NTHi-Mcat-001 study. For corticosteroids, this will mean prednisone ≥ 20 mg/day, or equivalent. Inhaled and topical steroids are allowed.
  • Administration of long-acting immune-modifying drugs at any time during the study period (e.g. infliximab).
  • Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product (pharmaceutical product or device).
  • Administration of immunoglobulins and/or any blood products during the period starting 3 months before the first follow-up visit or planned administration during the study period.
  • Current alcoholism and/or drug abuse.
  • Has significant disease (including significant neurological or psychological disorders), in the opinion of the investigator, likely to interfere with the study and/or likely to cause death within the study duration.
  • Any other condition that the investigator judges may interfere with study findings.
